` To all whom it may concern.'

4Be it known that I, Monnls U. Bnnnnnrn, a citizen of the United Statesresldlng at (.in'cinnati l in the; county ofllamllton and 5 State ofhio,. have invented certain new and useful Improvement in ConveyingSystems, of which the following is a specificaltion.' A, f. l I

VThis invention ,relates to elevators and moreiparticularly toenelevator-- adapted to bein conjunction withliad as an element of aconveying system. y i

The purpose of the present invention 1s to provide an improved elevatorof this nature 15 constructed to ebperate with' endless travelinglapronsarranged end to end in such manner.' that said aprons'and the elevator'provide' means which safely and rapidly transfer filled bags or-theraokages along a level of readily variable `ength and inA readilyvariable'directions and from said levelto a diiferent one, and which isadapted to ltransfer-siich packages from lwagons or cars' andpilethesame in any vpart of the room of "a Warehouse or other'place ofstor? age or from suehstorage places'v to wagons or cars or fromone partof a room `to another part of the saine room or from'fone' roo'm toanothery roornon a different level. While it is intended to claim4herein the elevator, I will describe in detail the construcltion andoperation ofthe system as a whole because the marked Iadvantages of theelevator forming the'subject matter ofthis application can `best beappreciatedby aftl10r-V oughnnderstanding of the cOnditionsn-nder'Awhich itis used as well as the manner of using the same. The systenrofwhich this 'elevatorA `forms apart is characterized by. the

40 factsz .y i i Fi'rstythat it .compr1ses a serles of readily.separabler, and 'unitable movablei,.sections,K

each?` having a frame, anendlesstrveling ..ap1on'ashaf t which`extendslengthwise of shaft a1idtheapron 'adapted 'to' impart-:posi- 4tive movement gto the4 ylattenin.tli'eg direction 'of the length of theshaft,` and 1'miv'feijylial` connections between the confrontingends ofl the several sections. whereby oneoifsaidmAl shafts will 'be driven byanother and will impart thel describedtraveling move-- menttothe apronof its section,"

the frame, drivngeonnections between the` the same to the foregoingsections, and hasl a. discharging slide, `tbeoileliverin `end of whlchis adjustable laterally as We l as ver# tically for delivering bags fromthe elevator to a predetermined place Within the range torage pile'being'n of its adjustments, to a s built up by the system.

The parts are alsocharaoterized by features entering into the i detailsthereof,

whereby important advantages in respect ofA strength', effectiventilizationof power, port"-l ability, andI ease of disconnect-ions vofsec 1 tions and their assemblage into a system of the 'required length,extending in required `directions to and 'from any requiredplace,"

are secured, all as will hereinaftenfully ap` pear.

These slats serve as thesupport forthe filledbags whereby upon its rotation V1t will impart'travel-ing movement to the latter in the direction of the length of theshaft, and also has at its end anelement 840i a universal connection,the mate 8a of which is carried 'by theconti'guous end of the similar'shaft 5 of the next section A.
